The ANSER by Littlite may look familiar but Littlite's included some unique features designed to make the ANSER the most powerful, versatile and energy efficient compact task light on the market. The ANSER uses a single, warm white LED coupled with the ultimate CC (Constant Current) dimming circuitry and we packed it in a new lineal (end-out) gooseneck configuration. The CC circuitry converts input voltage of 5-28vdc and feeds 12-Volt to the LED. Power the ANSER from our standard 12-Volt external power supply or any other source of 5-28vdc power. As a bonus, the ANSER can be powered from most USB ports.
